The scheme design is how to solve the odor and power consumption caused by pouring in the workshop on the fourth floor.
1. Chemical composition of insulating paint: formaldehyde, toluene, dimethyl ester, etc.
2. Schematic diagram of workshop energy saving
Exhaust gas purification process
The odor generated by pouring is quickly collected by the energy-saving and environmentally-friendly fan in the hood, and the particulate matter above PM2.5 is simply filtered out by the primary and intermediate filters of the new fan, and then the odor is absorbed by the activated carbon filter to be discharged to the floor.

Note: 3.7kwx8 hours=29.6x30 days=888x1.1 yuan/degree=977 yuan; 22.5kwx8 hours=180x30 days=5400 degrees/month x1.1 yuan=5940 yuan.5940-977=4963 yuan x 10 months = 49630 yuan / year power saving
Summary
1. Now investing 35,750 yuan in one time, 7 months of photovoltaic expenses can be saved back;2. The suction speed is more than double that of the original one, and the smell of the workshop is also improved, which is helpful to the employees.
3. You can apply for the national subsidy policy for the workshop environment transformation, about 30% of the project transformation amount.
